Kidney shaped brim of the pelvis is known as

Appeared in: UPPSC 2022

Explanation

The Android pelvis has a brim that is described as heart-shaped or triangular.
This shape is due to a prominent sacral promontory that indents the posterior aspect of the pelvic inlet.
This indentation gives the brim a shape that is often compared to a heart or a kidney.
This type of pelvis has a narrow anterior portion, which can make fetal head engagement and descent difficult during labor.

Option A: The Gynecoid pelvis has a round or slightly oval-shaped brim, not a kidney shape. It is the most common and most favorable shape for childbirth.
Option C: The Anthropoid pelvis has a long, oval-shaped brim, where the anteroposterior (front-to-back) diameter is greater than the transverse (side-to-side) diameter.
Option D: The Platypelloid pelvis has a flattened, wide, transversely oval brim. Its key feature is a short anteroposterior diameter and a wide transverse diameter.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Caldwell-Moloy classification of pelvic types as background academic context rather than a clinical decision trigger.
Understanding pelvic shapes is crucial for nurses and midwives to anticipate potential difficulties during labor and delivery.
An Android pelvis is associated with a higher risk of labor dystocia (difficult labor), deep transverse arrest, and the need for operative delivery (forceps, vacuum, or cesarean section) because the narrow fore-pelvis can impede the rotation and descent of the fetal head.
During antenatal assessment, clinical pelvimetry can give an indication of the pelvic type, helping the healthcare team to prepare a birth plan and counsel the woman about the potential course of labor.

How to Approach the Question

First, identify the key term in the question: 'Kidney shaped brim'.
Recall the Caldwell-Moloy classification, which describes four main types of pelvic shapes: Gynecoid, Android, Anthropoid, and Platypelloid.
Associate the characteristic shape of the pelvic inlet (brim) with each type.
Gynecoid is round.
Android is heart-shaped or triangular.
Anthropoid is a long, front-to-back oval.
